AC - Alternating current, the type of electrical current produced in a rotation generator alternator , which changes both magnitude and direction. Measured in volts. The speed or number of times it changes direction in a second is called frequency. Industry standard on frequency is 60 cycles per second, which means the electricity changes direction 60 times per second.
Transmitter, receiver, transmission medium — these are the basic elements that make up a communication system. Every human being is equipped with a basic communication system. The mouth and vocal cords is the transmitter, ears are the receivers, and air is the transmission medium over which sound travels between mouth and ear. The transmitter and receiver elements of a data modem such as the type used in a traffic signal system controller box may not be readily visible.

Despite the benefits of UHVDC transmission lines, the suggestion of a Chinese-built global electricity grid has been a cause for concern for some observers, as the Belt and Road Initiative in general has been. Are we likely to see a global megagrid materialise? Constructing a colossus The Changji-Guquan transmission line is a colossal feat that will be able to transmit 12,MW of power, or enough to meet the needs of
Glossary and Acronyms
It extends the scope of traditional control systems to include all automation functions within a single operations and engineering environment. Actuator: In electrical engineering, the term actuator refers to a mechanism that causes a device to be turned on or off, adjusted or moved, usually in response to an electrical signal. In some literature the terms actor or effector are also used. Actuators enable computers to control complex manufacturing processes without human intervention or supervision. Advanced process control APC : In general terms, advanced process control refers to large-scale computer systems that are used to monitor and control processing plants such as cement factories or oil refineries. The systems extend traditional process control, which is used to monitor and control individual processes, by evaluating and controlling multiple processes across the plant. By monitoring multiple processes, APC systems can optimize operations for multiple parameters, evaluating the impact each adjustment will have on neighboring operations by referencing current and historical data.

Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant , to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery , known as the " power grid " in North America , or just "the grid". A wide area synchronous grid , also known as an "interconnection" in North America, directly connects many generators delivering AC power with the same relative frequency to many consumers.
Немедленно. Это приказ. Чатрукьян замер от неожиданности. - Но, сэр, мутация… - Немедленно! - крикнул Стратмор. Чатрукьян некоторое время смотрел на него, лишившись дара речи, а потом бегом направился прочь из шифровалки. Стратмор повернулся и с удивлением увидел Хейла.
